the fronts look like coilovers but the rear...Im not too sure about. They might have just taken off the sleeve to showcase the shock body. Id contact H&R directly before I plunk down any change.
Some other options you might want to look into are:
1) if youre prepared to break the bank www.truechoice.com is the ONLY way to go. They have some of the sweetest setups...god if only I had a job.
2) Koni makes a nice coilover set as well b16a2pwr has a set ask him what he thinks of em.
3) dont break the bank and just buy a set of Koni/Tokico/etc shocks and some Ground Control sleeves. This is the route Im going with since I cant afford True Choice and Ground Control will allow me to customize my spring rates. Im going to go for 350front 400rear with an 8 spring height. This should help reduce understeer alot more and still be nice on the road.
